FIGURE 12

As with many types of technology if it is not used properly and/or 

proper  precautions  are  not  taken  there  is  the  potential  for  injury 

or harm.  This is especially true with UVC light due to the fact that 

it does not physically hurt at the time of exposure.  While UVC is 

very effective at breaking down grease molecules, direct exposure 

to large amounts is harmful to skin and eyes. The amount of UVC  

generated  in  these  hoods  is  greater  than  that  what  results  from 

direct exposure to the sun. Under no circumstances is it acceptable 

to view the lighted lamps without proper eye protection or expose 

bare skin directly to the light.   All interlocks and safety precautions 

called for in this manual must be followed to avoid the potential for 

harm to service personnel and/or operators. In addition, only trained 

and  authorized  personnel  may  perform  some  maintenance  See 

previous page for details.

Personal Protective Equipment

1. 

Eye protection that prevents 100% of UVC  being transmitted 

through the lens must be worn at all times when performing 

service work on any Ultima Vent that is energized and/or has 

the potential to be energized and expose personnel to UVC 

light.

2.  Whenever service work is performed it is recommended that 

long sleeve pants and shirts be worn to minimize the potential 

for inadvertent exposure of the skin to UVC.

Safety Interlocks

This product comes equipped with the following sensors to verify that 

all access doors are in place and that the exhaust fan is running:

1. 

Mechanical door switch on the UV Access door to ensure that 

the door is closed

2.  XG Extractor magnetic switches to ensure each extractor is 

installed.

3.  Air Pressure switch to verify air flow and exhaust fan 

operation

All of these devices must be working and/or adjusted properly  in 

order for the system to operate properly.
